Nikolaj Bjorner 87d4ce2659 working on #5614 
there are some different sources for the performance regression illustrated by the example. The mitigations will be enabled separately:
- m_bv_to_propagate is too expensive
- lp_bound_propagator misses equalities in two different ways:
   - it resets row checks after backtracking even though they could still propagate
   - it misses equalities for fixed rows when the fixed constant value does not correspond to a fixed variable.

FYI @levnach

regression from adding lambdas in model
 2021-08-31 12:13:27 -07:00
Nikolaj Bjorner 09696e989e add missing lambda defs per #5509 
the result is now unknown because the nested expression contains exists, which doesn't get replaced by universal quantifier which is assumed by the legacy core.
The legacy core should not depend on universal quantifiers only, but fixing this is a risk. Workaround is to rewrite goals using forall only (replace exists by de-Morgan dual).
